Overview

Tinnitus is the medical term for hearing sounds that aren’t actually there. People with tinnitus may notice ringing, buzzing, humming, or clicking noises that come from inside their ears or head.

These phantom sounds can vary in pitch and intensity, and be often most noticeable in quiet environments or at night. For some, they come and go, while others may experience them almost constantly.

Tinnitus is not a disease itself, but a symptom that can result from various underlying causes, such as hearing loss, ear injury, exposure to loud noises, or certain medical conditions.

While it is often mild and easy to ignore, tinnitus can sometimes become persistent and disruptive, making it difficult to concentrate, relax, or fall asleep. This can affect a person’s mood, stress levels, and overall quality of life.

Prevalence

Tinnitus is a surprisingly common condition. A 2024 report in the U.S. found that approximately 11% of adults experience it. This means that more than 1 in 10 individuals live with some form of ongoing sound in their ears or head.

For some, this internal sound is intermittent, coming and going. However, for a significant portion of those affected, it's a constant presence. Around 41% of tinnitus patients report that the sound is there continuously, all day, every day.

Persistent tinnitus can disrupt sleep, make it harder to concentrate, and affect both mental and physical well-being.

While tinnitus can affect people of any age, it is more frequently reported among older adults. Nevertheless, regardless of age, when tinnitus persists, it is more than just a minor annoyance; it can become an integral and challenging part of daily life.

Types

Tinnitus isn’t experienced the same way by everyone. It can vary in sound, cause, and how it affects daily life.

Subjective Tinnitus

• Most common type.
• Only the person affected can hear the sound.
• Often linked to changes in the inner ear, such as age-related hearing loss or long-term exposure to loud noise.
• The sound may be constant or occasional, and can last for weeks, months, or even years.

Objective Tinnitus

• Rare form of tinnitus.
• The sound has a physical source in the body (e.g., muscle spasms or blood vessel issues).
• Can sometimes be heard by a doctor using a stethoscope.
• Because it has a measurable cause, it may be easier to diagnose and treat.

Pulsatile Tinnitus

• Characterized by a rhythmic sound that often matches the heartbeat.
• Usually related to changes in blood flow near the ear or head.
• Some describe it as hearing their own pulse in one or both ears.

Somatosensory Tinnitus

• Linked to body movement or tension, especially in the head, neck, or jaw.
• The sound may change or become more noticeable with certain movements, like turning the head, clenching the jaw, or pressing on the neck or face.
• Thought to involve nerve pathways connecting muscles and the auditory system.

Temporary or Situational Tinnitus

• Sometimes tinnitus is short-lived, such as after exposure to loud music or machinery.
• This type usually fades after a few hours of quiet.
• For some, however, tinnitus becomes chronic, with no clear trigger or end.

Symptoms

Tinnitus doesn’t sound the same for everyone. The most common symptom is hearing a sound that isn’t coming from an external source.

• Ringing
• Buzzing
• Humming
• Clicking
• Hissing
• Whooshing
• Pulsing (often in sync with the heartbeat)

The sound can be constant or it can come and go. Some people notice it in just one ear, while others experience it in both. The volume can also vary, from a soft, barely noticeable hum to a loud noise that disrupts daily life.

In more severe cases, tinnitus may lead to:

• Trouble sleeping
• Difficulty concentrating
• Irritability
• Sensitivity to noise
• Anxiety or a low mood, especially if the sound is constant

For some, tinnitus is a mild annoyance. For others, it becomes a constant and exhausting experience that affects daily life.

Causes

Tinnitus can originate from various parts of the body, though the ear is most often involved.

Ear-Related Causes

• Ear infections (inner or middle ear)
• Fluid buildup or a perforated eardrum
• Ossicle issues: Damage to the small bones behind the eardrum can disrupt sound transmission.
• Earwax blockage: Can distort sound and trigger ringing or buzzing, often relieved once cleared.

Hearing Loss

• The most common cause of tinnitus.
• Damage to tiny hair cells in the inner ear due to aging, loud noise, or both alters sound signals.
• The brain may compensate by generating phantom sounds.

Other Physical Causes

• TMJ disorders: Jaw joint issues can affect nearby auditory nerves.
• Head or neck injuries: May impact nerves or blood flow near the ear.
• Tumors or nerve disorders: Rare, but can press on hearing pathways or blood vessels.

Risk Factors

While tinnitus doesn't always have a clear cause, certain patterns stand out.

Noise Exposure

Being around loud sounds for long periods can strain your inner ear, increasing your risk of hearing changes. This includes using headphones at high volumes, working near engines or machinery, or attending frequent concerts.

Age and Existing Hearing Loss

As hearing naturally fades with age, the risk of tinnitus tends to rise. The risk also increases if you already have some form of hearing loss, regardless of its cause.

Medications

In some cases, medications may be involved. A few drugs can trigger ringing in the ears as a side effect, though it's uncommon. Examples include aspirin, acetaminophen (Tylenol), and loop diuretics like furosemide (Lasix). If this happens, the sound might stop once the medication is adjusted or discontinued, but not always.

Having one or more of these risk factors doesn’t guarantee tinnitus will develop, but the risk increases with cumulative exposure or age.

Diagnosis

Tinnitus is usually a symptom of another underlying issue, so diagnosis focuses on identifying its cause.

• Initial Evaluation: Begins with a physical ear exam to check for wax buildup, infection, or abnormalities in the eardrum or middle ear.
• Hearing tests: Audiological exams help determine if hearing loss is present, which is commonly linked to tinnitus.
• Additional Tests
  • Blood tests may be ordered to check for thyroid problems, low iron, vitamin deficiencies.
  • If jaw pain or clicking is present, a referral to a dentist may be made to evaluate for TMJ disorders.
  • Imaging tests (MRI or CT scan) might be recommended if tinnitus is only in one ear, or there is concern about nerve issues, blood vessel abnormalities, or tumors

Treatment

There is no universal cure for tinnitus, but several strategies can help manage it.

Sound Therapy

For many, sound is part of the solution. Playing low background noise can help mask the ringing. This can come from a white noise machine, a smartphone app, or a wearable sound generator. Even soft music or nature sounds can make a difference. If hearing loss is a factor, hearing aids may be beneficial. They amplify outside noise, which can make the tinnitus less noticeable.

Behavioral Therapies

Others may benefit more from behavioral therapy, such as CBT (cognitive behavioral therapy) or tinnitus-focused therapy. These therapies don't eliminate the sound but can help reduce how much it bothers you and improve sleep, focus, and mood.

Medications and Supplements

There are no medications designed for tinnitus. However, doctors may prescribe something to help if it's significantly affecting your sleep or mental health, such as an antidepressant or anti-anxiety medication.

Some people try vitamins or herbal remedies often advertised as cures. However, it's important to know that there's no strong evidence that any supplement can effectively treat tinnitus.

Finding what works best often takes some trial and error. The goal isn't always to make the sound disappear, but rather to make it easier to live with.

Prevention

While tinnitus isn't always preventable, there are things you can do to lower your risk.

Protect Your Hearing

Loud noise is one of the most significant contributors. Wearing ear protection in noisy places like concerts, construction sites, and loud workplaces can help. Turning down the volume when using headphones is also crucial.

Stay Informed

Scientists are also studying the genetics of tinnitus, collecting data from patients with tinnitus and age-related hearing loss. The goal is to find genes that might increase the risk. If researchers can identify these links, it could transform how we approach tinnitus, leading to early detection, new treatments, and possibly even prevention strategies.

In the meantime, basic habits still matter. Avoid noise damage, be aware of medications that can affect your hearing, and get your ears checked if something doesn't feel right. While tinnitus can't always be stopped, in many cases, it can be avoided or its effects significantly reduced.
